Urban infrastructure, climate change, disaster and risk: lessons from the past for the future

Abstract

Narratives of lost cities and the exploration of ruins have captivated scholars and travellers for hundreds of years with explanations for their demise ranging from invasions to cataclysmic environmental events. This article explores three case studies to consider the impact of climate change, disaster and risk on urban infrastructure in the past, as well as to reflect on potential lessons of adaptation and resilience for modern cities and their inhabitants. The first examines the degree to which historic urban infrastructure can tell us about seismic adaptation in pre-modern Nepal, as well as recognising the increasing challenges to vernacular architecture from climate change. The second, Sri Lanka�s Medieval cities in the North Central Province, examines the intricate relationship between the ancient city of Anuradhapura and its artificial hydraulic landscape, a relationship which saw resilience defeated by irreversibly engineered adaptation. The final example is drawn from the experience of another tropical society on the other side of the globe, the low-density urban Classic Maya of Central America, which offers different yet relevant insights into alternate urban lifeways, both ancient and contemporary. Focusing on issues of successful and unsuccessful adaptations in urban settings over an archaeological time range and evaluating how archaeologists and historians have explored and presented this evidence, we conclude by considering how archaeology and archaeologists can also play a greater role in future sustainable urban planning.

Evidence of Climate Change Impacts in Sri Lanka - A Review of Literature

“…The erratic precipitation patterns and regular, intense rainfall incidents adversely affect drainage and sewage systems, leading to urban flash floods (Lo & Koralegedara, 2015). Furthermore, it accelerates the deterioration of infrastructure facilities (Coningham & Lucero, 2021).…”

Ancient Maya reservoirs, constructed wetlands, and future water needs

“…Clean water and political power were inextricably linked as demonstrated by the fact that the largest reservoirs were built near palaces and temples. Royals thus were busiest and the most powerful in the dry season when everyone needed clean drinking water ( 74 ). Kings’ role as water managers (e.g., using tribute labor to upkeep reservoirs) was to provide clean water and to perform the crucial rain and water ceremonies propitiating ancestors and gods such as Chahk, the Rain God.…”
